When water in your St. Louis kitchen tastes odd, leaks, or runs weak, the first question is often who should look at it. A homeowner can spend days bouncing between the water provider, a plumber, and the filter seller without getting closer to an answer. This guide sorts the common situations so you know where to start.
If you see water near an electrical outlet, smell gas, or notice a leak that is spreading fast, stop and deal with that first. Shut off power to the area if it is safe to do so, and contact the right emergency service before you troubleshoot anything else.
Start With What You Can See
Before calling anyone, spend a few minutes under the sink with a flashlight and a dry towel. Note where water is, which valve is involved, and whether anything is wet after the faucet has been shut off for a while. Write down what changed and when. A simple note such as started after the filter change or only the cold side saves time for whoever you call next.
Questions About Water Coming Into the House
If the problem seems to start upstream of your kitchen, such as low pressure throughout the home, discolored water from every tap, or a strong chlorine smell from every faucet, the issue may be outside your fixtures. Water supply questions in St. Louis usually go to the water provider that serves your address. Ask whether there is planned work or a known issue on your street, and ask what their records show for your service.
Keep your questions specific. Ask whether anything changed on the main line recently, whether there were pressure complaints nearby, and whether they can confirm where your service line runs. Do not expect them to troubleshoot your filter, since that equipment is usually outside their responsibility.
Questions About Pipes Inside the Walls or Under the Floor
A plumber is the right call when water appears from a fitting, a pipe joint, a shutoff valve, or the wall behind the cabinet. Also call a plumber if a valve will not close fully, if a supply line is cracked, or if you are unsure which pipe feeds which fixture. A plumber can also tell you whether a supply or drain change is practical in your house before you buy anything.
Ask for a clear written description of the problem and the proposed fix before any work starts. Keep that note with your home records so the next person who works on the sink knows what was found.
Questions About the Filter Itself
If the trouble is at the reverse osmosis faucet, such as a slow fill, a drip after shutoff, or taste that changed after a filter change, start with the manufacturer's written instructions and any warranty paperwork you saved. Check whether the filters were installed in the right order, whether the storage tank behaves as the instructions describe, and whether the faucet handle is secure. Many of these checks are simple, and you can do them yourself without special tools.
When to Call the Water Provider Versus a Plumber
- Every tap is affected at once: call the water provider first.
- Only one fixture or the area under one sink is affected: check the filter, then call a plumber if the leak is in a fitting.
- Water is pooling on the floor or in the cabinet: shut off the local valve and call a plumber.
- Taste, color, or smell changed after a filter change: check the filter installation and paperwork first.
A Practical Order of Steps
- Write down what you see, when it started, and which taps are affected.
- Check whether the problem appears at every tap or only at one.
- Look under the sink for drips, loose fittings, or a wet cabinet floor.
- Call the water provider if the problem is house-wide.
- Call a plumber if you see a leak in a fitting or a valve that will not work.
- Use your filter paperwork for anything tied to the filter itself.
Keeping these steps in order stops a small question from turning into a long series of phone calls. Start close to the fixture, widen outward only if the evidence points that way, and keep your notes. That habit makes every later call easier for you and for the people helping your St. Louis home.
